It will thus be that the plate l ior other oquiv- 211211.15 stfucturo mnpiqfoi instead {hereof serves QWO functions, namely, protecting interior of fine car and the. rollers against the entrance of snow, ice-or other matter, and also holding the upper part of the door in proximity to the side wall of the car.

In Fig. 4 I have shown in place of the I flat plate 14 a Z-bar having its upper flange 17 bolted to the car side and projecting over the flange 13 of the Z-bar which is mounted upon the door. In this construction the central web'l8 of the Z-bar secured to the car Wall overlies the central web of the Z-bar secured to the door and the lower flange 19 of the Z-bar secured to the car wall ov'erlaps upon the outer side of the lower flange of the Z-bar which is secured to the car door.

By this means a more effectual protection ot the rollers and interior of the car is secured.

Another modification is shown in Fig. 5 in which a simple angle bar 20 is bolted to the car door 21 and a .Z-bar 22 is secured to the car wall above the door opening and extending to the side thereof as in the construction shown in Fig. 4.

All three of the structures described possees the advantages above recited and the principle of my invention includes all of these-arrangements as well as any similar combination of parts.

What I claim is: A car havlng a door opening, a series of rollers mounted in the car wall and extending over said opening, a door, a Z-bar haw mp one of its flanges secured to said door arhacent the upper edge thereof, the central FRED MIATHEWS.
